"An energy hog is an app that, across most devices, seems to use more energy than a typical app," said Adam Oliner, one of Carat's creators. "An energy bug is an instance of an app running on a particular device that uses far more energy on that device than on most other devices."

Once Carat identifies these, it offers recommendations to help a user get more out of his or her battery life.

McCloskey found out he had apps running in the background even when they weren't in use, like Yahoo news and a music app.

Once you identify what's zapping your battery, the solution can be simple: If you don't use it, lose it. The same goes for GPS, Wi-Fi and Bluetooth. Turn these off when you don't need them.

For things like email, Facebook and Twitter, check out your settings.

"Email is probably the easiest example. You can go in there and it'll say: 'How often do you want me to check your email... every one minute, five minutes, 10 minutes, once and hour?' So, setting those types of settings will cut down on battery usage," said McCloskey.

McCloskey said a few changes can really help your battery-life. It's a matter of prioritizing.

That way you save your battery, and you don't waste your money.
